Indeed. I guess OP was looking for something besides windows tho …

and I’m just teasing, of course. I’ve got several Linux hosts running right now, but I’m typing on Win11.

Um … because its windows. Really. Almost downvoted you for that.

I think what you are saying is that the project I linked won’t work for USB boot on a new EFI system. I imagine your assessment about EFI is correct, but I’m mostly interested in virtualized systems.

Their are several DOOM linux things out there. The version I’m working on builds out with busybox.

My eventual intent is to use DOOM agents as a load tester.
I’d like the ISO to boot, look for a local game, and join a bot to deathmatch.
And then the testing metric would be a simple count. How many dooms can it run?
I have lots of projects. I might finish that one some day.

We used to do this back in the day with Win95.
You could change their shell to Notepad or something, and then that’s all the computer would run.
It was a slightly moar advanced trick than stealing their mouse ball.

Ya there’s Arch. There’s NixOS. There’s still Slackware.
But have you heard of 9front?
9front is useless. You won’t be gaming or working with it.
Mostly, you’d learn how operating systems are constructed.

Or DoomOS or DoomLinux. It’s a basic linux system where DOOM is the shell.
I forked this and tried to get it running. Learned some interesting things. Still doesn’t work for me. :]
